On the QRM from the PC - no I dont get any (problematic) unless the loop= is within 3 metres or so of the loop - I have a 15m length of RG58= 50 ohm coax to the loop and the background iono/qrn masks any noise that= I comes from the unit - Ill take some screen shots and publish.
 
Even some 400m from the nearest power line I can see 60Hz harmonics and so= me PLC stuff so Ill have to go out into the Plains a bit further.
 
The aim perhaps is to look for W1VLF or other signals (yourselves) sometim= e in the future -
 
I did some VLF receiving stuff is Asia Pacfic countries over the= past few years - an example from China http://kl1x.com/vlfchina.jpg  and from the Polar regions= some 30 years ago.
 
 
I didnt get a lot of time last night as I was getting bitten by= mosquitoes and was wearing short trousers but we had thunderstorms&n= bsp;to our West which spoilt any long distance reception -so much so that= Alphas werent visible - The normal US and some other VLF stations were go= od enough. Ill wait for a quieter time and smother myself with "bug= dope" but the loop/preamp was producing good results (its very very quiet= ) -
 
 I used the loop right next to the Television to calibrate the receiv= er looking at the sync but I need to revisit this given some of the= comments about digital TV's.
